3x+2y=6 ==> (dikalikan 1 )
Jawab: Mencari nilai x
14x-2y=16
3x+2y=6
________
11x=10
x=10/11
Mencari nilai y
3x+2y=6
3(10/11)+2y=6
30/11 + 2y=6
2y=6-30/11
2y=36/11
y=11/36×2
y=11/18
2. x+4y=-5 ==> (dikalikan 2)
2x-y=10 ==> (dikalikan 1 )
Jawab:
Mencari nilai y
2x+8y=-10
2x-y=10
________-
9y=-20
y=-20/9
Mencari nilai x
x+4y=-5
x+4(-20/9)=-5
x+4(-9/20)=-5
x+-9/5=-5
x=-5+9/5
x=-16/5
nanti kamu tinggal buat grafiknya aja, karrna kan udah tau nilai x dan y nya berapa:)
